Polarization-Entangled Photon Source

The U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) is seeking information from industry providers regarding the availability of a polarization-entangled photon source based on spontaneous parametric down-conversion using a periodically poled lithium niobate waveguide. This sources sought notice, identified as NB676020-26-01970, is for market research purposes only and does not constitute a solicitation, obligation, or commitment to award a contract. NIST requires a system capable of accepting an external pump laser to generate high-quality polarization-entangled photon pairs, with delivery, installation, and training anticipated within 16 weeks of order receipt. Respondents must submit information by July 16, 2026, including company details, Unique Entity ID, SAM.gov registration status, size certification under NAICS code 334515, and any suggestions to improve the draft specifications. Responses are limited to ten pages excluding cover pages and commercial pricing, must be in Word or PDF format with 12-point font, and must not include proprietary, classified, or confidential material. Companies are encouraged to provide standard commercial pricing, suggest evaluation factors for a future acquisition, and confirm compliance with FAR clause 52.219-14 if they are small businesses and intend to pursue a total small business set-aside. Evidence of existing federal contracts such as a GSA Multiple Award Schedule must also be included if applicable. Team responses must include all required information for each participating entity. NIST will use submitted information to determine the most effective acquisition strategy and may publish a formal solicitation on SAM.gov or GSA eBuy afterward. Responses are voluntary, and NIST is under no obligation to award a contract or provide feedback. Information provided may be used for any legally appropriate purpose, and late submissions may not be considered.
